' e m emm 3 My 'invention relates to typewritingand like machines, and more particularly to 'pa per cuttingimean s'for cutting sheets from 'continuou'sfwebs fed through the machine. I 'T he main objectof my invention,"generallystated,' is to provide a simple and highly' efficient means of the-character specified], v y A further. object of vmyxinvention is to [provide paper cutting ;means which, when desired, may be readily'incorporated in existing, typewritingmachines suchas the 1 numbers 10, 11 and 12 Remington machines,

, without modifying or materiallymodifying the structural features of said"- machines as they now exist except'by the ready addition or substitution of a. few parts. I v

To the above and other ends which will hereinafter appear, my invention consists in of a standard'R emington machine equipped the features of construction, 7 arrangements i ofpar'tsand combinations of dev ces-set with the'paper *vention.

An upwardlyiextending ear :39 onithisgfbraoliet carries a pin 40 on "which is pivoted alink 4'1. This link is slotted longitudinally at 42 and extends rearwa rdly' along the inner side of the upward extenision on ,the relatiyelylrfiiied'plate 12; Se-

c'u-red to; and extending from theiright-hand faeeofthis extension of the plate 12 is a threaded pin'43 which v-may1be formed-as a continuation of :the pin 32'. A nut 44 with 'i a reduced shank 45 is threaded onto/the pin 43. :Jlih-e reducedpart '45 of the nut passes through the slot' linthe-link 4l and con- 7 completely over on its pivots535 tromthe" the blade is prevented from-turning in'the opposite direction on its pivotsbeyond the its Fig. lfposition, presenting the sharp edge of the blade foremost. On'the' other hand,

I Fig. -5 position by the link 41 which at this timehas the end wall 46 of its slot bearing against the stop 45; v a

Referring particularly to"Fig.-3, it .Wlll be seen that inthe normal position of the parts, the" bottom edge ofthe link 41 co-acts at 48 with theupper en'd of the arm 23. Therefore any tendency of theblade a at this ':time to turn on its pivots v35, so thatf'thke -.cutting edge of the blade will'move' away from the-platenpis prevented.- "'This is due to the fact that'the "forward end; of ithelink 41 is at this: time preventedfrom'moving down by the arm 23; and the'rear end of the link is prevented ifro nf mioving upby the stoprmember 45.; This positively holds the plate against turning upout of'its cut- 7 ting positionon the pivots under the action of the paper as it is being severedalong the line of-the sharpedge of thebla'de.

, v In the operation" of the mechanism, with the paper 6 inthe machine and the parts vdisposed as'shownin Fig. 2, the operator may at any time cut oil that portion off the work sheet which has been advanced beyond the blade by merely-drawingithe sheet fr r' m one side edge to. the other'over the sharp cutting edge of the blade? It:will;be seen that, as the partsappearinthis figure, the

blade a in a measure acts as a substitute' fo'r the feed rollers ordinarily carried "by" the arms 22 and 23; guiding the paper above the printing line and retaining it snug against the front face of the platen at the printlng l1ne.-,

7 When it is work sheet, it is merely necessary to depress the finger piece 26 to theiFig. eposition.

WVhen'the' operators'finger is removed from the key theparts will beloeked in the Fig, *5 position. In depressingthe key '26, the arm s22 and 23'1noved forward, but before their arrest the vlost motion of the link 41 relatively to the fixedlpart 45ceased; the end'wall 46 of'theaslot in the link reaching the stop 45. The result ofthis was to hold the pivot 40 against further advance .while the pivots'35 continued to advance with the by Letters Patent,"is

"platenf desired to introduce] a new 7 arms 2 2'and 23. This 'eflected a turning I of the blade a on itscpivots 35; to present the sharp edge 36 of the blade toward the platen in' the safety? position,',instead of presenting it uppermost where it might injure'the ;operator. The parts being locked in the position shown in Fig. 5', the-operator I may advance ithe work sheet or sheets through theienlargedf space between the blade and platenuntil the leading-,end'por'- tions of the sheets'arepwithin the range of the blade. Thefinger piece-34 may now be released, returning the parts-to the Fig. 2: position with the cutting blade in theefi'ec tive position ready at anytime to sever that portion otthe work sheet or sheets extending beyond. its cuttingedge.
